I installed on my motherboard ddr2 memories. I know that these memories want 1.8 v to work. My motherboard set their frequency at 800 mhz. Into the bios i read 1.98 v. If i set the frequency at 667 mhz i read 1.87 v. and at 553 mhz i read 1.82 v. I don't set manually nothing, the bios makes all the work. I don't know if this higher voltage can damage something or not.

A small variation in voltage is not usually a problem. The difference between your high and low readings is less than 10%. You also don't know how accurate the readings are.
